After the reverse design of the first-year-of-issue 1878 Morgan silver dollar was changed from 8 tail feathers to 7, the eagle`s design was also changed to the fuller "convex" or round breast (3rd Reverse). Only about 2 million of the 1878 Philadelphia Mint coins have this improved reverse design. This 1878 Morgan dollar will make a great addition to your collection - representing the first year of issue for the magnificent Morgan series!
